IMPROVEMENT IN OF KEOKUK, IOWTA.l

LAMP-BURNERS.

Specification forming part of Letters Patent No. 58,893, dated October16, 1865.

To all whom t may concern:

Be it known that I, JOHN F. SANFORD, of Keokuk, in the county of Lee andState of Iowa, have. invented certain new and useful Improvements inLamp-Burners; and I do hereby declare that the following is a full,clear, and exact description thereof, ret'erence being' had to theaccompanying drawings, making a part of this specification, in which-Figure l is a side elevation of the improved lamp-burner. Fig. 2' is aside view ofthe burner, showing the adjusting spur-wheel for moving thewick. Fig. 3 is a diametrical section of the burner. Figs. 4 and 5 aredevices for adjusting the spur-wheels up to the wick.

Similar letters of reference indicate corresponding parts in the severalgures.

This invention relates to improvements on lamp-burners which are adaptedfor lamps `that burn the hydrocarbonuids, and which are provided withrotary spur-wheels for adjusting the wicks in their tubes.

This class of lamp-burners is frequently reudercd worthless by thewearing out of the spurs upon the wheels which are used for adjustingthe wicks. Vhen the points of these spurs become dull, which they soonAdo, the wicks cannot be adjusted; and as these spurs are appliedpermanently within the cage of the burner, they cannot be readilyremoved therefrom; hence theimporlance of providing some means wherebythe spurs can be sharpened in the burners and also adjusted up to thewick in case they lail to act regularly upon it.

The nature-of lny invention consists in providing for the application ofa file to thespurs of lamp-burners for tiling these spurs sharp whenthey become dull 5 also in providing for setting up said spurs as nearas desirable to the wicks in tubes of lamp-burners, so that the spurscan be made to act regularly uponthe wicks for raising and loweringthem, as will be hereinafter described.

To enable others skilled in the art to understand my invention, I willdescribe its construction and operation.

In the accompanying drawings, A representsthe cageor body of the burner.Bis the cone thereof, and C is the wick-tube, within which the wick ismoved up and down by means of spur-wheels et a, that are appliedV toarod7 b, as shown in Figs. l, 2, and 3. These parts may be made in theusual well-known manner. The rod b, by which the spurs a c are adjusted,passes through the cage of the burner, and has its end bearing in aspringplate, Cf, which is secured permanently at its' lower end to thewick-tube C, its upper end being free from this tube, as shown in Fig.3.

The spring-plate G 1s slotted to allow the wheels a a to work freely,and the wick-tube C is also slotted to allow of the entrance of thecircumference of the said wheels, so that the teeth on the latter mayact upon the wick. The opening' through the. cage A for the rod b ismade suiiciently large to admit of the wheels a a being adjusted up tothe wick when desired. This adjustment of the spur-wheels will behereinafter described.

On each side of the two spur-wheels a c, I make openings g g through theperforated cage A, of sufficient size to admit through them aiile, G,(shown in red lines,) which is used for the purpose of sharpening theteeth or spurs on the wheels a a. Said openings are arranged directlyopposite each other and in a line with the spur-wheels, so that the filecan move freely through the cage during the act ot' sharpening theteeth.

As the spur-wheels are worn away by c011 tinued sharpening and use, itis found necessary to provide some means foradjustingthese spurs up tothe wick, so that they will always take hold of it. This device consistsin ap plying a yoke, h, around t-he tube C and securing it to the upperend of the spring-plate C', as shown in Figs. 3 and 5. The yoke has ascrew, i, tapped through it, one end of which l abuts against the tubeC, so that by adjusting this screw the upper end of the plate C', to-vgether with the spur-wheels a a, can be drawn up 5 or, if desirable, awedge, j, maybe used in conjunction with the yoke h instead of theset-screw for moving the spurs up to the wick.

I do not desire to confine myself to the use of the devices hereindescribed for adjusting the bearing-plate G' of the spur-wheels c c, asother contrivances may be adopted for effecting this object. I prefer,however, to adopt the plan shown in Figs. 3 and 5.

The openings g g through the cage A of the 2 :isses burner will admit ofthe lighting of the lamp without removing the chimney, by inserting alburning match or taper through said openings and moving it upward so asto bring the flame in Contact with the upper end of the wich-tube.

It' desirable, small sliding or hinged gates may be applied to theburner or cage A for closing the openings g g and g' when they are notrequired open.

I am aware that lampburners have been so constructed as to admit of thelamp being lighted through apertures in the cage or body of the burner.

I am also aware that other lamp-burners have been so constructed thatthe spurs on the wheels which move the wiel; may be sharpened throughapertures in 'the cage ot' the burners.

I am further aware that lamp-burners have been so constructed that bymeans of a screw and spring the wicks may be pressed more or -lessforcibly in the direction ot' the spur-wheel to regulate the iow of oil.i

None of these things, therefore, do I el aim, broadly, in and ofthemselves; but

What I do claim, and desire to secure by Letters Patent, is-

In a lamp-burner, such aconstruetion and arrangement of parts that whilethey admit of the sharpening ot' the spurs of the wheels which move thewicks, will also permit the lighting of the lamps through apertures inthe cage of the burners without the necessity ot' cont-rivances fordepressing the wicks for that purpose, substantially as above described.

2. In combination with apertures through the cage of a lamp-burner soconstructed and arranged as to admit the sharpening ot' the spurs uponthe wheels which move the wick without moving or displacing any of theparts, a contrivanee for causing these spur-wheels to engage with thewick, substantially as and for the purpose above described.
